Claims. (Cl. 99-171) This invention relates to a package wrapper. The invention is particularly useful in the provision of a capsule-equipped wrapper, whereby coloring matter or other material useful with the contents of the package may be broken when A desired for incorporation of the material with the contents of the package.

In the sale of uncolored oleomargarine, it is desired to provide means for supplying coloring matter which the housewife may readily mix with the oleomargarine. It is common to use a gelatin capsule for including the color ingredient to preserve it in air-tight condition and for incorporation in the oleomargarine.

Considerable diiiiculty has been experienced in the use of such capsules particularly for oleomargarine. Often the customer fails to receive a capsule or loses it. Very frequently, the capsule is broken on the Way home from the store, resulting in stained clothes, food, etc. If the housewifes fingers happen to be wet, the gelatin capsule may slip out of her grasp and become lost or become soiled before it is retrieved. Even when she is successful in breaking the capsule properly, it is substantially impossible for her to avoid getting her' fingers stained with the coloring matter. Forthe purpose of illustration, the invention will be described herein as being employed with oleomargarine.

An object of the present invention is to overcome the above disadvantages and provide a wrapper which at all times maintains the gelatin capsule in the desired position and in a position where it may be broken lwithout bringing the coloring matter into contact with the fingers. A further object is to provide a Wrapper equipped with an air-tight capsule which maintains the coloring matter or other material constantly out of communication with the contents of the package while, at the same time, confining the' shell of the capsule after the same is broken and permitting the contents of the capsule to mix readily with the contents of the package. Yet another object is to provide means which may be employed with a flat wrapping strip, while requiring no folds therein, for supporting a capsule within the air-tight wrapper but maintaining the shell of the capsule, after it is broken, out of contact with the contents of the package. A further object is to provide a package for the mixing of the oleomargarine and coloring matter or the fixing of any other similar substances while within the package, and also providing a package 'which may be expanded or contracted as desired in the mixing'operation. Other specific objects and advantages will appear as the specification proceeds.

The invention is illustrated, in preferred embodiments, by the accompanying drawing, in Which- Figure 1 is a perspective view of a package wrapper structure embodying my invention; Fig. 2, a top plan view of the wrapper prior to its being folded about a cake of oleomargarine or the like; Fig. 3, an enlarged transverse sectional view, the section being taken as indicated at line 3 of Fig. 1; Fig. 4, a bottom plan view of the capsule-enclosure sheet employed; Fig. 5, a plan view of a modified form of wrapper embodying my invention; and, Fig. 6, a perspective view of the modified structure shown in Fig. 5, providing an adjustable enclosure for oleomargarine and the like and useful in the mixing of the contents of the package.

In the illustration given in Figs. 1 to 4, inclusive, I0 designates a wrapper formed of any suitable ilexible material and preferably a transslucent material. Wrapper I0 is adapted to be folded about a cake II of olemargarine or the like. Secured to the top wall I2 of the folded wrapper is a capsule I3 containing coloring matter I4, or other material which is to be mingled with the contents of the package.

The capsule I3 is confined against the top wall of the wrapper by means of a retaining strip I5 which is preferably formed of thermoplastic material and which is provided with perforations I6. The application of a heating element along the line I'I causes a fusion between the thermoplastic members I0 and I5 and unitesvthe two, as illustrated more clearly in Fig. 4.

In the operation of the structure shown in Figs. 1 to 4, inclusive, the wrapper I0 is formed, as shown more clearly in Fig. 2, with the capsule I3 secured against the wall of the wrapper I0. The Wrapper I0 is then folded about the oleomargarine II or other suitable material and the capsule I3 is pressed downwardly so that it, together with the pocket of the member I5, is deeply imbedded within the oleomargarine or other body. With this structure, the capsule I3 is protected against breaking by'means of the body of oleomargarine thereabout while, at the same time, the capsule I3 is available from outside the package for breaking by means of a pinching movement.

The housewife may unfold the wrapper III, and in this operation, the wrapper III readily draws the capsule I3 out of engagement with the body of oleomargarlne cake II. The wrapper may then be placed over the body of oleomargarine the coloring matter to ilow into the oleomargarine without staining her fingers with the coloringmaterial. She can also eil'ectively apply the coloring material through the oleomargarine body by pressing the capsule portion of the wrapper I deeply into the body of the oleomargarine at spaced points.

An effective mixing of portions of the oleomargarine can .also be accomplished within l the wrapper I0 by holding it enclosed about the oleomargarine body and kneading the oleomargarine.

During all of the above operations for bringing the coloring matter into contact with the oleomargarine or other material, there is no chance for the capsule portions to become mingled with the oleomargarine, etc., body because these particles are confined by the strip I tightly in contact with the wrapper I0.

In the modiiied structure shown in Figs. 5 and 6, the structure is identicalv with that in Figs. 1 to 4, inclusive, except that one end of lthe wrapper I8 is extended laterally at I8. Further, in the structure shown in Figs. 5 and 6, I prefer to heat seal the wrapper I8 entirely around the oleomargarine body I I except at one extreme end of the member I9. In other words, as shown more clearly in Fig. 6, I provide a case or bag which entirely encloses the oleomargarine and is free only at the outer end.20. The neck portion formed by the extension I9 may be twisted as indicated by the numeral 2| in Fig. 6, to provide a closure for the end of the casing.

In the operation of the modied structure shown in Fig. 5, the wrapper may be placed about the oleomargarine cake or other material and is sealed thereabout so as to provide a complete enclosure except for the opening 20 at the end of the extension I9, thus open only at one-end. The freely extending portion I9 may be grasped by the housewife and employed for drawing the capsule I3 out of contact with the oleomargarine body in which it is imbedded. She may then break the capsule and then press the portion about the capsule deeply within the body of the oleomargarine to distribute the coloring matter therein. She may then further twist the extension I9 to form the twisted handle 2| and then proceed to knead the mass within the wrapper until the coloring matter Isuniformly distributed throughout the oleomargarine. Sometimes in the kneading operation, depending upon the material within the package and its viscosity, it is desired to have a relatively large forming a sack or bag space during the kneading operation, and in this instance the housewife may unroll the twisted handle 2| slightly so as to provide a greater area -within the package for the kneading of the material. At other times, it is desired to have: a smaller space within the package forthe kneading operation and the housewife may here tightly twist the extension I9 so as to provide a smaller chamber within the package for the material during kneading. v

It will be understood that the wrapper may be securedvaround the oleomargarine in a variety of ways and sealed about the cake in partial extent or not at all, as illustrated herein.

The twisted portion 2l of the modied wrapper or case I8 is effective not only as a means for regulating the size of the chamber in which the oleomargarine, etc., is being kneaded but also,

yit serves as a handle 4 to enable the operator to turn the case rapidly over during .the kneading operation.

Any suitable material for forming the wrapper vmay be employed. I have found that synthetic rubber or Vinylite are unusually good. Such materials lare not only translucent and thus enable the operator to see the progress of the coloring operation, but also, they are tough and stretchable to a degree. Further, they permit heat sealing about the contents. For the kneading operation, the synthetic rubber, Vinylite, etc., are particularly effective because of their resilience, and quality of immediate recovery after stretchgarine, a perforated ilexible' strip secured toan y inner wall of said web, and a frangible capsule held between said perforated strip and said inner wall of the web, said capsule containing coloring matter and the perforations of said strip V.being of a size toy permit the llow of said coloring matter, when the capsule is broken, into said oleomargarine while confining lthe shell of said capsule. v l

2. A capsule-equipped wrapper comprising a web of flexible translucent material suitable for enclosing a body of oleomargarine and for the kneading of the oleomargarine therein, said web having walls enclosing said oleomargarine and having wall portions sealed to each other in part and providing between them a chamber, the lnner of said walls about said chamber being perforated and the Vouter of said walls about said chamber being imperforata and a frangible capsule containing coloring material confined within said chamber and resting over said perforated area, the perforations in said wall permitting the ilow of the coloring matter therethrough when the capsule is broken while confining the shell of said capsule.. 'i

3. A package wrapper comprising a translucent web of flexible material adapted to enclose a body of oleomargarine and to be sealed 'thereabout to provide a closed package except at one end and said web being extended adjacent said open end to provide a closure when .folded and when the contents of said package are being kneaded, a strip of exible material secured to an inner wall of said package, and a frangible capsule containing coloring material between said strip and said wall, said strip having perforations therein permitting thel ow of coloring matter therethrough when said capsule is broken but confining the shell of the capsule between the strip and said wall;

4. An oleomargarine package comprising a transparent web of tough flexible material suitsaid strip having perforations therein permitting the flow of coloring material therethrough when said capsule is broken while conning the shell 15 of the capsule within said chamber.
